Description
【０００１】[0001]
本考案は、実験室用イオン濃度計の自動校正装置（以下、単に自動校正装置と 云う）に関する。 The present invention relates to an automatic calibration device for a laboratory ion concentration meter (hereinafter, simply referred to as an automatic calibration device).
【０００２】[0002]
実験室で用いる例えばｐＨ計は、種々の要因により不斉電位および感度が経時 変化するところから、測定前あるいは定期的に校正することが必要である。 A pH meter used in a laboratory, for example, needs to be calibrated before or periodically because the asymmetric potential and sensitivity change with time due to various factors.
【０００３】 従来は、 先ず、図３（Ａ）に示すように、イオン濃度測定部３１の先端に形成された 電極部３２に対して、純水容器３３内に収容されている純水３４を吹き付けるな どして、電極部３２を十分洗浄し、電極部３２に付着している液滴を除去する。Conventionally, as shown in FIG. 3A, first, as shown in FIG. 3A, pure water 34 contained in a pure water container 33 is charged to an electrode portion 32 formed at the tip of the ion concentration measuring portion 31. The electrode portion 32 is thoroughly washed by spraying, for example, and the droplets adhering to the electrode portion 32 are removed.
【０００４】 前記洗浄後、同図（Ｂ）に示すように、電極部３２をビーカー３５に収容し た校正用ｐＨ標準液３６内に浸漬する。After the cleaning, as shown in FIG. 1B, the electrode portion 32 is immersed in the calibration pH standard liquid 36 contained in the beaker 35.
【０００５】 そして、図４にも示したｐＨ計本体３７の表示部３８を見ながら、指示値が 安定するのを待つ。Then, while looking at the display section 38 of the pH meter body 37 also shown in FIG. 4, it waits until the indicated value becomes stable.
【０００６】 このとき、校正液３６の温度を温度計３９によって測定し、そのときのｐＨ 値をテーブル（図外）で読む。At this time, the temperature of the calibration liquid 36 is measured by the thermometer 39, and the pH value at that time is read in a table (not shown).
【０００７】 ｐＨ計本体３７のつまみ４０を操作して指示値がテーブルのｐＨ値になるよ うに調整する。The knob 40 of the pH meter body 37 is operated to adjust the indicated value to the pH value in the table.
【０００８】 なお、前記ステップを終了しても、必要により、ステップに戻って、ステ ップからステップまでのステップを繰り返すようにすることもあった。Even if the above steps are completed, the process may return to the steps and the steps from step to step may be repeated if necessary.
【０００９】[0009]
しかしながら、上記従来の校正方法は、測定前または定期的に行われるもので あるため、本来の測定に先立ってオペレータがそのための時間を余分に見込む必 要があると共に、全てのステップが手動によって行われるものであるから、その ための人手が必要であると云った不都合があった。 However, since the above-mentioned conventional calibration method is performed before or at the time of measurement, it is necessary for the operator to allow extra time for the measurement prior to the actual measurement, and all steps are performed manually. However, there was an inconvenience that it required manpower for that.
【００１０】 本考案は、上述の事柄に留意してなされたもので、その目的とするところは、 従来、手動で行っていた校正操作を、実験室用イオン濃度計が本来のイオン濃度 測定に用いられる時間ではなく、所謂そのオフタイムに自動で行なえるようにし た自動校正装置を提供することにある。The present invention has been made in consideration of the above-mentioned matters. The purpose of the present invention is to make a calibration operation, which was conventionally performed manually, into a true ion concentration measurement by a laboratory ion concentration meter. It is to provide an automatic calibration device that can automatically perform so-called off-time rather than the time used.
【００１１】[0011]
上記目的を達成するため、本考案に係る自動校正装置は、先端に電極部を形成 したイオン濃度測定部を着脱自在に装着することができるチャンバと、制御コン トローラによって制御され、前記イオン濃度測定部が装着された状態のチャンバ に対して、所定の順序で洗浄水、校正用標準液を供給する切換え供給装置と、前 記チャンバから回収される廃液を回収する装置とから構成されている。 In order to achieve the above object, the automatic calibration device according to the present invention is controlled by a chamber to which an ion concentration measuring unit having an electrode portion formed at the tip can be detachably mounted and a control controller to measure the ion concentration. It is composed of a switching supply device for supplying cleaning water and a calibration standard solution in a predetermined order to the chamber in which the parts are mounted, and a device for recovering the waste liquid recovered from the chamber.
【００１２】[0012]
例えばｐＨ計の場合においては、溶液のｐＨ測定を行うときは、イオン濃度測 定部の先端に形成されている電極部を溶液中に浸漬する。これにより、溶液のｐ Ｈを測定できる。 For example, in the case of a pH meter, when measuring the pH of the solution, the electrode part formed at the tip of the ion concentration measuring part is immersed in the solution. This allows the pH of the solution to be measured.
【００１３】 そして、前記イオン濃度測定部は、ｐＨ測定以外のオフタイムには、チャンバ に装着される。イオン濃度測定部が装着された状態にあるチャンバに対して、所 定の順序で洗浄水、校正用ｐＨ標準液が供給されることにより、ｐＨ計が無人の 状態で、自動的に校正される。Then, the ion concentration measuring unit is attached to the chamber during the off-time other than the pH measurement. By supplying washing water and pH standard solution for calibration to the chamber in which the ion concentration measuring unit is installed, the pH meter is automatically calibrated in an unattended state. .
